Double-Gable Garden Extension

The starting point was a generous open footprint at the back of a timber-clad family home, already dug and slabbed, with the brickwork plinth running out around the perimeter.

We brought the shell up in blockwork off the brick plinth, set out the new openings, and tied the gable peaks into the existing house — keeping the new mass in proportion with the original timber elevation.

From there it was a traditional cut roof: rafters, purlins, hips and valleys cut on site over a double-pitched plan, with gang-nail trusses spanning the main run and loose rafters on the smaller gable.

Inside, we framed the stud partitions, formed the new doorway through to the existing kitchen in blockwork, and ran the first-fix services in the ceiling void ready for the trades behind us.

The roof was finished in slate-grey concrete plain tiles over a breathable membrane and counter-battens — handed back watertight, with a clean line into the original main roof.
